Since the era of great water engineering works in South Africa, there has been a major shift in the thinking and approach to water resources management. Previous focus on water supply has been replaced by demand management ...

This paper analyses a study aimed at testing the cost effectiveness of designing a hub and spoke network (H&S network”) for Africa that allows airlines to reduce the costs of travel and increase connectivity. Various hub ...

Underground mine automation has the potential to increase safety, productivity and allow the mining of lower-grade resources. In a mining environment with both autonomous robots and humans, it is essential that the robots ...

Worldwide, fatigue has been cited as a contributory cause in heavy vehicle crashes. In South Africa very little scientific evidence is available to support or reject this notion. A study was commissioned to investigate the ...

Climate change is projected to lead to warmer temperatures, especially in southern Africa, where the warming is predicted to be 2°C higher than the global increase. Given the high burden of disease already associated with ...

This paper investigates how the measurement of a network attack
taxonomy can be related to human perception. Network attacks do not have a
time limitation, but the earlier its detected, the more damage can be prevented
and ...

Human adaptation and response to drought is primarily through evasion or endurance. A review of historical agricultural practices in southern Africa demonstrates evidence of drought evasion response strategies in ...

Biomedical Optics is the study of the optical properties of living biological material, especially its scattering and absorption characteristics, and their significance to light propagation within the material. Determination ...

Despite electrification, over 90% of rural households in certain areas of South Africa continue to depend on fuelwood, and this affects woody vegetation structure, with associated cascading effects on biodiversity within ...

The science of supply chain management in business has advanced so much in the last ten years, especially through the use of IT. How can knowledge be used to help in the humanitarian context, where no science of disaster ...

The incorporation of several different types of fibres into a single matrix has led to the development of hybrid biocomposites. The behaviour of hybrid composites is a weighed sum of the individual components in which there ...

A fully-coupled partitioned fluid-structure interaction (FSI) scheme is developed for sub- and transonic aeroelastic structures undergoing non-linear displacements. The Euler equations, written in an Arbitrary Lagrangian ...

A methodology for the inverse design of non-lifting axisymmetric bodies in compressible flow is presented. In this method, an inverse design approach based on conformal mapping is used to design a set of airfoils in ...

To date, the South African electrification programme has been highly successful from a policy, institutional, planning, financing and technical innovation perspective. The focus on electrification and energisation, though, ...

One of the South African Government’s objectives is to have universal access to electricity for all of its citizens (Mbeki, 2004). To date, the South African electrification programme has been extremely successful from a ...

The authors propose an agent architecture which combines Partially observable Markov decision processes (POMDPs) and the belief-desire-intention (BDI) framework have several complementary strengths. The authors propose an ...

A general description of the study area be found in part 1(Chutter, 1970), where the fauna other than Cladocera and Copera of store-in-current, marginal vegetation and story backwater has been described. It was found that ...

Vaal Dam is situated on the elevated plateau which forms the interior of South Africa and is a little less than 1500 m above the level. The source of the most of the streams and rivers flowing into the dam are about 2000 ...

The Western Karoo depends entirely on groundwater for domestic and agricultural use. An understanding of the chemical evolution of the groundwater provides insight into the interaction of water with the environment and ...

For the past 20 years management of the Bot/Kleinmond estuarine system in the south-western Cape has been based on the premise that, barring intervention, the estuary was naturally evolving into a freshwater coastal lake. ...
